I have an idea that's been stewing in my head for awhile but first I need additional input.
I've read that both Fanning and Parker believe that chatroulette has the potential to become big.
I think that once they've fixed the obvious problems, what's left will be a big group of people nexting and nexting 'til they encounter the very limited pool of attractive or interesting people using it. Doesn't sound very fun.
Is chatroulette a fad that's over?
I think the notion of turning chatroulette into a performance platform is very interesting. Some of the Ben Folds chatroulette performances were pretty fascinating and managed to get at the one-to-many-ness necessary to drive large amounts of traffic on a consumer site (you don't need that to make an interesting product--but Skype seems to have nailed 1 to 1 video pretty well). Being able to have different bands 'battle' on chatroulette or have comics or musicians present new material could be great.
